RAW VIDEO: Our cameras were there as alleged Snapchat shooter Mason Kirby Gray, 20, was taken to the Harris County inmate processing center on Commerce.

Our cameras were there as Gray was escorted in handcuffs by deputies, and the 20-year-old seemed suddenly camera shy.

Detectives said after Eyewitness News aired surveillance video last week that allegedly shows Gray at the robbery scenes, they received a tip that led to his arrest. Gray now faces armed robbery charges.

Investigators said last week they received information from the Snapchat video that identified Gray as the suspect who robbed a Valero station at gunpoint on Wednesday, March 1, 2017, in west Harris County.
